Had 2 out of 3 kids home sick from school today so decided to take the day off and tinker with the wind chime project.
I decided that the effort to jerk with trying to prime and then paint EMT was probably more hassle than what it was worth and in all likelihood would in fact dull the sound.
I picked up a short piece of EMT and 10ft of 1" copper. I constructed one note from the plans I had with the EMT and then used a set of formulas found in yahoo group which allows you to determine the same for other types of metals, widths, and thicknesses to make modifications based on different material.
I then tested the resulting sounds, one against the other. This worked out quite well and I was pleased with the result of this first test piece so I fashioned the remaining notes for set one.
Further, I've decided not to paint the copper at all....cleaned up my first set of pieces with mineral spirits and then gentle scrub with some extra fine steel wool. The finish looks great though it will weather over time but I think I will go this path.
I'm making several so I cut what remaining copper I had for what will become the second set and then went to task cutting out all the tops, strikers from some nice red oak and made sails for the bottom.
I'll trek back to hardware store this weekend and get the balance of copper I need....
...oh, yes, less I forget....
....and some foam insulation and duct tape for the set I am shipping to Zakk.
Cheers!
